Frequently Asked Questions
Can AI tools replace legal research?
AI tools like Lexis+ AI and Harvey dramatically accelerate legal research — summarizing case law, identifying relevant precedents, and drafting research memos. But they cannot replace attorney judgment: AI hallucinates citations, misses jurisdictional nuance, and cannot assess how a judge in your specific court tends to rule. Use AI to find and synthesize research, then verify all citations and apply your legal judgment.
Is it ethical for lawyers to use AI?
Yes, with appropriate supervision and disclosure where required. Most bar associations have issued guidance permitting AI use with proper supervision. The duty of competence may actually require lawyers to understand and consider AI tools. Key obligations: verify all AI output, do not share privileged information with non-compliant AI tools, and check your jurisdiction's disclosure requirements.
Which AI tool is best for contract review?
Spellbook is purpose-built for contract review in Microsoft Word — it flags risky clauses, suggests market-standard language, and drafts missing provisions. Harvey is best for law firms needing a full legal AI platform. For solo practitioners handling consumer contracts, Claude or ChatGPT with a carefully crafted review prompt can provide a useful first pass at lower cost.
